页面元素在窗口的中间位置

var winWidth = $(window).width();
var winHeight = $(window).height();
var x = (winWidth - 382)/2 + $(document).scrollLeft();
var y = (winHeight - 280)/2 + $(document).scrollTop();

 

时间区转换

 

function calcTime(city, offset) {
	d = new Date();
	utc = d.getTime() + (d.getTimezoneOffset() * 60000);
	nd = new Date(utc + (3600000*offset));
	return "The local time in " + city + " is " + nd.toLocaleString();
}
alert(calcTime('Bombay', +5.5));
alert(calcTime('Singapore', +8));
alert(calcTime('London', +1));

 

把文本框焦点移动到文本最后

function setInputFocus(elementId){ 
	var inputElement = document.getElementById(elementId); 
	if(!inputElement){ 
	   return;
	} 
	
	var textRange =inputElement.createTextRange(); 
	textRange.moveStart('character',inputElement.value.length); 
	textRange.collapse(true); 
	textRange.select(); 
}
